commit 0930bb46bbbb43afe3381ece2cb2f8a5bc3fb544 upstream.This patch adds the product ID of Huawei's Vodafone K4510 mobile broadbandmodem to option.c. This is necessary so that the driver gets loaded on demandwithout the intervention of usb_modeswitch. This has the benefit of it becomingavailable faster and also ensures that the option driver is not bound to anetwork interface that should be claimed by cdc_ether.
